"Create operation is not supported by Actor entity" error on creating Note

When I fire this request

I get this response

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
soap:Body

</soap:Body>
</soap:Envelope>

I referenced this for the body schema

Any help on what the message means? Does it mean that the CreatedBy actor is not allowed to create notes? I tried other ActorType enumerations with the same result.
